Title: Optical reader
Inventor: NAKADA YASUO
IPC: G02B7/02
Filed: 1985-03-29
Abstract: PURPOSE:To correct variation in the focal length of an image forming element such as a lens array due to temperature variation by shifting at least either the image forming element or an optical signal reading element such as a photodetecting element in position in a direction of the optical axis. CONSTITUTION:When respective lenses 2a-2c rise in temperature, the respective lenses in the array increase in thickness and decreases in refractive index owing to coefficients of thermal expansion and the quantities of variation in refractive index per temperature. This means that the refracting power of the optical system decreases and the focal length increases as the temperature rises. The paraxial focus position is expressed by 1/a+1/b=1/f, where (f) is the focal length, (a) is the distance from an object point to the front principal point of the lens system, and (b) is the distance from the rear principal point of the lens system to a paraxial image point. Consequently, an increase in focal length (f) with temperature is corrected by increasing the length from the position of an original 1 as the object point to a lens surface or from the lens surface to a photodetection surface 3 as the image point.

Title: Image forming device
Inventor: OSAWA SHIGENOBU
IPC: G03G15/043
Filed: 1987-03-23
Abstract: PURPOSE:To permit image formation of a part of an original at a gradation characteristic different from the gradation characteristic of the other part by changing an AC developing bias frequency of a developing means to change the gradation characteristic and assigning the prescribed range of the original where the gradation characteristic is to be changed. CONSTITUTION:The region of the outside edge Wb in the frame W of the original G is assigned as the erasing range for low gradation copying and the part except the region of the inside edge Wa is assigned as the erasing range for high gradation copying. The image from which the region of the outside edge Wb is erased and the image from which the part except the region of the inside edge Wa is erased are respectively stored in a memory. The image erased of the region of the outside edge Wb is then copied on paper with the AC developing bias off. The image from which the part except the region of the inside frame Wa is removed is then copied on this paper with the AC developing bias on. The image is, therefore, formed at the low gradation on this paper in the part of the original G except the range enclosed by the outside edge Wb and the image is formed at the high gradation in the part within the range enclosed by the inside edge Wa. The formation of the easily visible and sharp image is thereby permitted.

Title: High-speed and high-torque selecting type spindle head
Inventor: KONDO HIDEO
IPC: B23Q5/14
Filed: 1986-03-28
Abstract: PURPOSE:To reduce mechanical loss, noise and vibration, and enable high-load machining, by transmitting the rotation of an apertured driving motor directly to a main spindle with a clutch closed upon high-speed rotation of the main spindle, while transmitting the rotation of the motor through a reduction gear mechanism to the main spindle upon high-torque rotation of the main spindle. CONSTITUTION:In the case of high-speed rotation, a sliding clutch 2 is moved in the direction of A to engage clutch claws 3 and 4 with each other, and gears 19 and 22 are moved in the directions of B and C to release the mesh with gears 5 and 12, respectively. Accordingly, the rotation of a rotating shaft 7 of an apertured driving motor 6 is directly transmitted from the gear 5 through the sliding clutch to a main spindle 29, thereby rotating the main spindle 29 at highs speeds. In the case of high- torque operation, the engagement of the clutch 2 with the gear 5 is released, and the gears 19 and 22 are meshed with the gears 5 and 12, respectively. As a result, the rotation of the motor is transmitted through the gears 5, 17, 18, 23, 24, 21 and 20 to the gear 12, thereby greatly reducing the rotational speed and transmitting a high torque to the main spindle 29. Accordingly, the mechanical loss, noise and vibration are reduced, and the selection of high-speed rotation and high-torque transmission may be effected.

Abstract: PROBLEM TO BE SOLVED: To make determinable the permittivity of a dielectric by projecting electromagnetic wave to the dielectric, receiving reflection wave for a buried reflector, image-processing obtained two-dimensional plane data and changing parameters corresponding to wave transmission velocities. SOLUTION: The permittivity measuring device 1 is put on the ground or concrete surface being a dielectric and a microwave is emitted from a sensor part 2 toward underground. The reflection wave of an object 6 buried underground is operated for processing with an operation processor 3 and two-dimensional display image data and three-dimensional display image data sliced in the depth direction are indicated on a display 4. Here, the wavelength transmission velocity ν of radar wave as a factor to obtain the burying depth Z0 of the object 6 of an underground radar is obtained from ν=2×Z0 /t (t: return time of reflection wave of the object 6) with the operation processor 3. This wavelength transmission velocity ν is changed as parameter and a wavelength transmission velocity ν where an image is most clearly obtained is selected.  The permittivity εr is obtained by ν=c/√ εr (c: light velocity) in the operation processor 3.

Title: Heat image apparatus

IPC: G01J5/48
Filed: 1987-03-24
Abstract: PURPOSE:To perform high speed scanning high in mechanical reliability, by using a two-dimensional infrared detector composed of a plurality of infrared sensor elements of two-dimensional arrangement. CONSTITUTION:Infrared rays are condensed by a condensing system 12 to be formed into an image on a two-dimensional infrared detector 1. This detector 1 generates the electric signals corresponding to the intensities of the infrared rays respectively received individually by a plurality of infrared sensor elements. Each of these electric signals is successively read on the basis of the synchronous signal of a timing generator 29 and inputted to an A/D converter 4 to be converted to a digital value. The intensity of the infrared rays emitted from a body to be tested correlates with the temp. of the body to be tested but is not the temp. itself of the body to be tested and, therefore, an infrared image signal is converted to a temp. image signal. This conversion is performed by a linearizer 3. The output of the linearizer 3 is subtracted from the data of a memory 7 by a subtractor 30 and divided by an arbitrary constant by a divider 31 and again added to the data of the memory by an adder 32 to be outputted. By this method, a high speed scanning can be performed.
